SAW-SYETTIKNG MACHINE.

Speccaton of Letters Patent.

Application led. October 19, 1914.` Serial No. 867,551.

To all 'whom t may concern Be it known that l, EDGAR VE. LINCOLN, acitizen of the United States, 4residing at Los Angeles, in the county ofLos kAngeles A further object isto provide a machiney provided with apair of co-acting dies, removable from the machine at will for thepurpose of substitution and means for lock*V ing the said ydies inoperating position in the machine.

`A. further object is to provide aimachine having a single operatingmember adapted to act uponand set a plurality of saw teeth at a singleoperation thereof.

A further object is toprovide amachine having adj ustable meansforrestingthe saw blade and holding the blade firmly in position duringa setting operation.

A fiu'tlieiobject is to provide a machine of simplilied construction,capable of beingy constructed and sold to the trade at a low cost and ofbeing used as a stationary or portable iixtureon a work bench or table.@ther objects may appear inthe description. f n A My machine partakessomewhat yof the form and character of an ordinary hand op-y eratedpressk and is provided with a pair of oppositely mounted setting dieshaving saw tooth seats formed in adjacent sides thereof, one of saiddies being movableand the other being stationary, and said tooth seatsbeing alternatelyinclined rfrom the'r front to the rear side ofthe diesand the relative positions oit' the two die members being. such thatopposite tooth seats will correspond asto their inclination. The sawblade'is adapted to be placed between the two die members in such amanner that the teeth on the saw will register with the tooth seats onthe lower member and the rear edge thereof` will rest upon an adjustableblock which ris provided on the basefor holding the saw:

blade lirmly in position.

` Referringto the drawings, in which similar characters of referenceindicate the same parts throughout the several figures, Figure l is aplan of my machine with a portion of the operating handle broken away;`Fig. 2 is a sectional elevation of the same on the lineQ-Q, Fig. 3; Fig.3 is a side elevation; Fig. l isa sectional elevation of the base andextensible saw rest, on the line 4.-4,

3;' Figp is a face view of one of the die members; Fig. 6 is a sectionof Fig. 5 on the line 6--6; Fig. 7 is a section of the same on the line7-7g and Fig. 8 is a sec' tion of the same on the line 8-8.

As shown in Figs. 1, 2 and 3, 1 is a suitable basey upon which all ofthe mechanism ismounted and which is provided with the lower extendedportions 2 and 3 having the bores 3 and 4- in their extremities, throughPatented Dec. 7, 1915.

which suitable bolts or screws may be in- ,i

serted for securing the machiney to ka work bench ortable. rllheextension 3 is provided' on eachside witha groove 5 of rectangular crosssection, as shown, or otherwise, and these'grooves are adapted toslidably receive the tongues on the inner sides ofthe opposite and.parallel arms 7 of the saw rest 8 which isprovided with an upwardly`eX- tending `flat portion 9 adapted to receive and holdy the outer edgeof a saw blade. rlhe arms 7 extend inwardly toward the center of thebase 1 from theblock portion 9 and are provided at the top with flateXtensions'9 adapted to slide upon the top of the base extension 3 andserve as'an additional guide for the saw rest 8. ln the form of baseshown, which is adapted to be secured rigidly yto a work bench ortable,`it isnecessary to countersinh the vertical bore A in theextension 3, as at 10, to provide a seat for the head of the bolt orscrew in order that the saw rest 8 may be moved longitu-V dinally `overthe full length of the base extension 8. f

loo

The central portionof the base 1 has a verticalextension 11 with anoutwardly projecting lug 12 on one sideV and a pair of opposite lugs laon the other side thereof, be-A tween the latter of which ythe handle 16is v,adapted to be pivoted ona pin or screw 15 ksecured in the lugs 14.A vertically disposedy die holder 17 is `biifurcated at the upper endand pivotally secured to the handle 16 by 11e means of the pin or screw18, the handle 16 being held between the furcations 19 and 20,

the central portion of the die holder 17 being slidably seated in asuitableV verticalaperture 13 in the lug 12, and the lower portion 21thereof carries a die member 22 which is slidably seated in a lateralgroove 21 extending the full width of the die holder 17, and is adaptedto be locked and held in a stationary position onthe die holder by meansof a pin 22 which may be inserted in suitable bores in the die holder 17and in the upper side of the die member 22. similar die member 23issimilarly seated in a i groove 23 in the flat upwardly extendingportion 2 on the base 1 and isv adapted to be held in a stationaryposition by means of the pin 24k in the side of the extension 2% similarin function and mountf ingto the ,pin 22 in the die holder 17. Thev dieseats 21 and 23 in the die holder 17 and the extension 24, respectively,may be dovetailed, as shown, or of anyy other form adapted to hold thedie members rigidly in wardly from the frontyedges ofthe die members,both forms of the seats being angular to conform to the shape of the sawteeth and separated by the angular iat spaces 27, as shown in Figs. 5,6, 7 and 8.v

Thus the tooth seats 25- are in the form of depressions in the dies andthcseats 26. are in ythelform of raised extensions from the facethereof.

The lower die member 23 is slightly longer than the upper die member 22and is provided with an extra tooth seat, by means Lof which the saw maybe properly set between the dies at the beginning of or at any timeduring a saw setting operation, by placing the last tooth which has beenpreviously set,

or `the first tooth at the end of the saw on` the extra tooth seat sothat theremainder of .the teeth between the dies may register with thetooth seats thereon.` f

VAs a limiting means for the die holder 17 I may provide a flatV toppedlug 28 on the base 1, as shown in Fig. 3 the upper side of theI lug 28being adapted to be engagedby the lower end of the die holder 17. Thedie members 22 and 23 are designed to be tightly fitted into the grooves21 and 23,respec tively so that when once placed in position in themachine the jar or movement thereof may not cause a movement of the diesin their seats and move them out of registration, the pins 22and 24serving as an ad-y ditional and positive locking means therefor. It,shouldbe understood that a number of sets of dies ofdiiferent pitch Vmaybe providedwitheach machine corresponding to the'pitch'of the teeth ofdifferent size saws, as'ordinarily used by mechanics in the trade, andthat when the dies are correctly placed in position in the machine, thetooth seats 25 of one of the die members will register with the toothseats 26 of the other vdie member.

lnl operation, when` a saw blade is placed in the machine so that thetoothed edge lies between the two die members 22 and 23 and the outeredgey of the blade rests upon the block! 9, care being taken thattheteeth of the blade rest in and are in positive registra-v tion with thetoothA seats in upper face .of the lower die member 23, the handle 16may be depressed soas to force thevupper die member 22 firmly againstthe upper edge of the teethrin the saw blade andthe 4lower die memberV23 iny Contact with thelower edge of the teeth. rThis operation .willcause a number of thesawy teethl equal to the number of toothrseats on`the die members .to be properly set to correspond to the diesand'likewise, yas before stated, the sawbla'deA being moved so that .thelast of the set teethf registers with the extra toothr seat.on..thelower die member 23, more teethmay be set, and soon untilithe sawAhasbeenv placed inthe properconditionfor use.

The form of my invention may be changed in someof ythe minor particularswithout. departing from the spirit of my inventionv as defined in theappended claims Yorenlarging kthe scope thereon; and as lhereinbeforestated, some minor `alterations may beanecf. essary in order to adapt4the machine to usev as` a portable fixture.
